Find and pull your biggest growth levers with experimentation.

We run your CRO operation—from research and prioritization to implementation, measurement, and analysis.

How we find Breakthroughs Again and Again

Breakthroughs rarely come from testing more things. They come from understanding why people choose, hesitate, or walk away—then finding the few decision factors that can materially change that choice. Only then do we double down on what works and synthesize what we learn, so each experiment builds on the last.

* Wins under 7% stay out of the calculated compound lift. We count only gains we can defend, so the headline does not overstate the actual lift.

For a consumer-health brand, we owned research, tracking and testing end to end. The wins answered buyers’ worries about cost, coverage and next steps, and made the first impression more relatable.

    Working with Iman has transformed our approach to funnel optimization. His dedication and problem-solving skills are evident in the tangible improvements we’ve seen since we began collaborating 3 years ago. Thanks to Iman, we’re not just managing changes; we’re leading in our industry.

  • Maxwell AndersonCo-founder & CEO, Natal AppReviewed Jul 2026

    Iman is absolutely top notch. He is knowledgeable and patient, which is the perfect combination. … Very impressed. Excited to continue working with him

  • Daniel ChCEO, ThumbnailTest.comReviewed Feb 2024

    Iman has gone the extra mile - and even beyond that. He's super super patient, but knows all his stuff about Posthog, A/B testing, CVR and I feel like I've only scratched the surface. But leave that aside - many people know a lot. Iman's attitude is what really made the difference for us. This much professionalism can trump sometimes even skill - but Iman's got both. Already discussing a further contract, so I highly recommend him.

  • Wes OudshoornCo-founder, AppSignalReviewed Mar 2024

    It was a pleasure working with Iman! He has deep knowledge of Posthog and brings a ton of experience.

    He went straight into practical mode on our call, and we set up our analytics much better.

    I'll definitely hire Iman again in the future, and you should too :)

  • Olivier MaesCo-founder & CEO, BaserowReviewed Jan 2025

    Great working with Iman!

  • Sam EmaraFounder, Foxy AIReviewed Aug 2024

    Iman was a pleasure to work with. He has deep technical expertise and knowledge, and is able to operate at the high velocity required in a startup environment. We'll work with him again, and highly recommend him

  • Sam PerrinsCo-founder & CEO, Pixie WingReviewed Dec 2024

    Iman did some great work for us on our CRO over several months. He provided quality test ideas and was proactive in delivering updates on their progress. During his time with us we saw an increase in our conversion rate as well as more stable conversion with less fluctuation. Recommended for anyone looking for help with improving CR on their eccom store.

  • Pablo Sanchez-ArriolaCreative StrategistReviewed Feb 2025

    When we had a huge course launch, he set up dozens of test variations, allowing us to dial in the perfect price point, headlines, VSL versions, CTAs, and other key sales page elements. … When it comes to CRO, analytics, and pretty much ANYTHING related to the technical side of funnel optimization, you simply won't find anyone better than Iman!

  • Amanda SpannFounder, The App AcceleratorReviewed Jan 2024

    Hire this guy TODAY! I initially connected with Iman in regard to creating a funnel for me but his role evolved into a consulting capacity. He really went above and beyond, making himself available on an on-going basis, providing incredible insights and additional documents and just over delivering on my ask. I HIGHLY recommend him and think hes a fantastic contractor to work with. 5 stars!

  • Peter BokhorstCEO, Hummingbird MediaReviewed Apr 2026

    Iman set up our full tracking stack across 4 WooCommerce stores, including Hyros, PostHog, and Meta/Google conversion tracking. He was thorough, communicative, and proactive in solving issues with the Hyros engineering team. Delivered a clean, reliable setup that we can confidently base our ad spend decisions on. Would work with him again.

  • Jeremy NagelFounder, Focus BearReviewed Dec 2023

    Iman is a Posthog gun! He helped us with a tricky task (setting up stickiness ratio) and gave some great advice on funnel optimisation. Will be hiring him again for more advice.

  • Ben HizakCo-founder & COO, CherreReviewed Aug 2024

    Great experience

  • Ewald van WeesTracking and optimization engagementReviewed Jun 2025

    We're ending the contract with Iman simply because the project has been successfully completed. Working with Iman felt like having an additional team member—reliable, trustworthy, and fully accountable. … Iman takes full ownership of tasks and proactively suggests improvements to enhance the end result, all while respecting the agreed budget and deadlines.

  • Arsh SanwarwalaCEO, ThrillXReviewed Mar 2024

    Iman was of great help over a consultation call regarding CRO. I got a ton of clarity after speaking with Iman and he had a lot of patience walking me through the answers I needed help with. I'd highly recommend Iman for anyone looking for CRO help and a strong communicator.

The right decision, built the right way.

Iman Nazari

Iman cracks the code of audiences.

The biggest black box in a business is why its visitors do what they do. Iman reads it through research and experiments, then names the few edits with the highest return.

Moein Heshmati

Moein does things reliably.

Moein turns complexity into order. He architects the tracking, reporting and deployment behind the work, so every insight rests on verified data and every result holds up when someone checks.

We publish what we learn.
